books that are popular girl/outcast boy

I’m looking for books where the girl is well loved, well off in life, with a sunshine type personality. while the boy is shy, keeps to himself, and seen as odd by others. books with characters like hadley and archer in 27 days. but with a boy that’s less of an asshole and more just shy with a bad habit of blushing. books like if I’m being honest by emily wibberly.

probably a very small amount of books that have what I’m looking for as it’s usually the other way around.
